To all whom it may concern:

Be it known that I, GEORGE E. WHITNEY, a citizen of the United States, residing at 'Boston,in the county of Suffolk and Commonwealth of Massachusetts, have invented an Improvement in Automatic Multiple Oilers for Motor-Vehicles, of which the following de-- scription, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In steam automobiles there are frequently provided two steam pumps, one, for instance, to renew the air supply used to force the liquid fuel to the burner, and the other used to fill the boiler, the latter being more frequently an auxiliary pump to be used only in the event of the disabling of the main power pump commonly operated from the crosshead of the engine. Some means is usually provided for lubricating the steam cylinders of these pumps, each cylinder commonly having its separate lubricator. To avoid the expense attending the use of separate lubricators, and, at the same time, to economize in the use of the lubricant, my present invention comprehends means for supplying lubricant to both cylinders from a single lubrieating device, also means for admitting lubricant to the piston, for the time being in operation, and cutting it off from the inoperative piston.

To enable my invention to be understood, I refer to the accompanying drawings, wherein,

Figure 1 illustrates in vertical cross section partially broken away a portion of a motor vehicle equipped with means illustrating my invention; Fig. 2, a plan view of the pressure actuated controlling device; Fig. 3, a longitudinal section on the dotted line, 3-3, Fig. 2 showing the controlling device in an inverted positionyand, Fig. 4, a side view of the device, Fig. 2, viewed from the rear.

Referring to the drawings, in the particular embodiment of my invention there shown, A represents the body of a motor vehicle equipped with a boiler, B, to which is connected an engine, herein shown with its cylinders in a bay window or jacket, b, on the boiler,

said engine being adapted for the operation of the vehicle in the usual manner.

F and G indicate the steam cylinders of two direct acting pumps, the former being a boiler feed pump delivering through a suitable feed pipe, f, into the boiler, and supplementing the pump, f, operated by a lever,

' f adapted to be connected with the crosshead of the h, provided with two controlling valves, indicated respectively at h and k From the valves k h lead respectively the pipes, h, M, which enter opposite ends of the controlling device, m, shown separately in Figs. 2 to 4, inclusive. This controller, m, see Fig. .3, at one end, as at the left is internally threaded to receive the nipple, m, to the outer end of which the pipe, k is attached by a suitable union, while at its opposite end said controller is threaded at 'm. to receive a union, in, holding the nipple, m, to which the pipe, k, may be attached. Within the controller is a longitudinal passage, m from which lead two outlets, m, m which leadrespectively to the two steam cylinders, G, F, to supply the same with steam for the operation of the usual pistons therein.

The longitudinal passage, m contains a ball valve, m adapted to roll back and forth therein and to be seated at one end, at the left, as viewed in Fig. 3, against a seat, m formed in the end of the extension, m", on the nipple, m, and at the opposite 'end, at the right, against the seat, m, formed in the wall of said passage. The lubricator is indicated at L, Fig. 1, its lubricating pipe, 1, under the control of the valve, 1, entering the controller at Z between the outlets m and m therefrom.

Referring again to Fig. 1, the valves k and k are controlled by a single T-shaped device, 0, pivoted at o, and connected by a rod, 0 with the operating lever, 0 When the operating lever is in the posiadmit steam past said valve through the pipe h, to the controller, m, thence through the outlet, m", to the cylinder, F, to operate the piston therein. The action of the steam thus admitted to the controller will move the ball valve 711. to the right, as viewed in Fig. 1; or, as in Fig. 3, to the left, against its seat, m as shown in dotted lines, to prevent the passage of steam to the outlet, m and to the cylinder G, and also to prevent the flow of lubricant from the lubricatorto the said pipe, m, and cylinder G. So long as the valve m is in its position, Fig. 3, the lubricant will enter the cylinder F only, so that no lubricant is wasted by escaping to a cylinder in which the piston is not in operation. When, however, the operating device, 0 is reversed, and the stem of the valve,.h is depressed to admit steam through the pipe M, to the cylinder, G, the ball valve, at, will be moved to the left, as viewed in Fig. 1; or, to the right, into its full line position, as viewed in Fig. 3; against the seat m, thereby preventing steam from entering the cylinder F, also cutting off the supply of lubricant thereto. So long as the ball valve remains in its full line position, Fig. 3, lubricant will flow to the cylinder G only.

-tion, Fig. 1, the stem of the valve k is depressed'to The lubricator, L, may be of any suitable or-usual I type but preferably of the well-known condensation displacement type, relying upon the ad mission of steam under pressure to its reservoir to cause oil to be fed therefrom, this type being preferable because it feeds the oil only when pressure is on. Thus, when both the valves, k and h are closed, and no steam admitted to either pump cylinder, there will be no pressure upon the lubricator no flow of oil therefrom; and admission of steam to either cylinder will operate to start the feed of oil from the lubricator, which, by means of the ball controlling valve described, will pass only to that cylinder the piston of which is operating, and the instant the pressure is cut off to stop the operation of said piston, the flow of oil likewise stops. Any .other suitable or equivalent lubricator may, however, be used, and when arranged according to my invention, sufiices fora plurality of cylinders supplying oil to the cylinder only which is .for the time beingin use. Such working devices as the two pumps herein described, I have termed differentially operating devices; that is to say, they are subject to individual operation lacking co-incidence either in time or rate or both, the several devices being operated, for example, at separate times, or'for periods which are neither co-extensive orc'oincident, or at unlike and variable rates.

My invention is not limited to the particular embodiment-thereof here shown and described, and obviously it maybe used in connection with any other group of differentially operating working devices than the particular devices, viz., steam pumps, herein shown and described.
